Hey Dav,
I may be wrong but I don't think the basic Array type has any support
whatsoever for compression. You'd want to go with CArra

All arrays have metadata. You can set it like so (f is a pytables
file):
annotated = f.createArray('/', 'annotated', [1,2,3])
annotated.attrs.name = 'Spam'
annotated.attrs.really = True
annotated.attrs.frac = 0.123
Again, not as fast / indexed as a table, but if you're loading it all

I feel like this is the same (only?) message I always send to people
on the list...
Have you considered simply storing each item as a separate atomic
array? Then you don't need to mess with any of this VLArray stuff, or
tables at all. I know it's called PyTables, but you can actually get
Okay, I'm completely confused. I've gone through the docs and there
are many examples, but I can't find anything as simple as I want.
Maybe I'm not using the right tool?
In it's simplest form, I have a large number of (name, np array)
tuples. (I happen to store them in a dict, and the np

I have an elementary question.
I have a dictionary with about 10,000 keys. The keys are (shortish)
strings. Each value is a time series of structured arrays (record

total data size isn't huge, about 1GB.
